IMPROVEMENT IN B OLSTERS FOR SPINNING-FRAMES.

Specification forming part of Letters Patent No. 159,034, dated January 26, 1875; application filed December28, 1874.

' fication:

In the accompanying drawings like letters indicate like parts. I

Figure l is a perspective view of my invention. Fig. 2 is a vertical section of the same, with the spindle entire. Fig. 3 shows the bolster detached from the oil-cup with the wick in position.

The purpose of my invention is to afford perfect lubrication of the spindle without waste of oil. Hitherto the oil, after working its way down through the bolster, has been lost; but by using my invention I not only secure cleanliness, but also, by retaining the oil, utilize it all in a continual lubrication. The bolster commonly used needs frequently to be oiled, but mine requiresoiling only at very long intervals, and thereby a great saving of both material and time is eifected.

My improved bolster consists of two parts, the bolster proper, marked A, and the oil-cup B, which are fastened together by a screwthread. At the upper end the part A is hollowed to form a receptacle, into which the oil is poured. Within the cylinder is alongitudinal slot, a, passing from the eye b down throughout the tube, and continuing below to the lower point of the projecting piece or finger c, as appears in Fig. 3. Along this slot or groove lies the wick d, of cotton or other suitable fibers. Being wholly within the slot, the wick does not interfere with the revolution of the spindle C. The oil, after being poured into the upper receptacle, 6, works itself downward through the bolster A, and, flowing over the collar D, which surrounds the spindle, as shown in section in Fig. 2, falls into the oilcup B, and is there retained. The form and construction of this oil-cup appear in Fig. 2. The finger c, threaded with the wick, is thus submerged in the oil. The wick draws up the oil by capillary attraction, and so is saturated throughout its entire length, and lies as a lubricating surface in contact with the revolving spindle, maintaining a constant and uniform lubrication between the bolster and spindle, and utilizing the oil to the fullest extent without any waste, and with entire cleanliness.

I claim as a novel and useful invention and desire to secure by Letters Patent- The bolster A, with its inclosed wick 61 and finger c, in combination with the oil-cup B and collar D, substantially as shown and for the purpose specified.
